Abstract : Electrolytic processes were developed for applying a lead-tin coating on the effective area of aluminum monometallic and bimetallic bearings of various engines. Depending upon the composition of the alloy from which the bearings have been made, various methods of preparing the surfaces of aluminum alloys before the application of the run-in coatings were investigated and employed. In order to eliminate the phenomenon of gripping of the steel bearing surface of bimetallic bearings with coupled surfaces of the unit, a process of chemical nickelizing is employed. (Author)
